To all whom it may concern.

Be it known that we, JosnrH JoULn, a citizen of the United States, and a resident of Belleville, in the county of Essex and State of New Jersey, and Crrsntns ALBERT Coors, a subject of the King of Great Brit ain, and a resident of Belleville, in the county of Essex and State of New Jersey, have jointly invented certain new and useful Improvements in Looms, of which the following is a specification.

The invention pertains more particularly to improvements in the lay and means connected or associated therewith for imparting motion thereto for making the beats, the lay preferably forming a so-called long beat and a short beat at each operation. e illustrate our invention as embodied in a loom for weaving wire cloth of the character required for use in paper making machines, this wire cloth being of very fine mesh and requiring the utmost uniformity throughout its extent.

The loom illustrated in the drawings pre sents some well-known features, these being the warp beam, breast beam and cloth beam, and also the lay beam frame with the exception of the features provided thereon for carrying out the present'invention.

I In accordance with our invention we provide springactuated means co-acting with cams on the lay beam frame for causing the lay beam to make its beats against the weft, and we also provide cam-controlled means for returning the lay beam frame to its initial or rear position and permitting said frame to move forwardly at the proper periods for making the beats. Our inven tion thus pertains more particularly to the lay motion or means for operating and controlling the lay beam-frame, and this invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanyingdrawings, in which:

Figure 1 is a substantially central vertical section through a loom equipped with the features of our invention but otherwise of known construction;

Fig. '2' is a horizontal section on an enlarged scale through a portion of the same taken on the dotted line 22 of Fig. 1;

Fig. 3 is a horizontal section, partly broken away, through a portion of the same taken on the dotted line 33 of Fig. 1;

ence of the spring to cause the lay to perform its beats. 1

In the drawings 10 designates the usual corresponding side supporting frames for the loom parts; 11 the customary warp beam; 12 the breast beam; 13 the cloth beam; 1 1 the lay beam frame comprising the vertical side portions 15 and connecting transverse beam 16, and 17 a transverse beam affording a tramway for a magnetic shuttle carriage 18 of known type, all of the features just mentioned being well-known in this art with the exception of certain earns 19 which, in accordance with our invention, we secure to the side members 15 of the lay beam frame 1 1. 20 denotes the usual warp strands or wires.

21 designates the driving shaft upon one end of which is mounted a belt wheel 22 to be driven by a belt, not shown, as usual. The driving shaft 21 is connected with and actuates an auxiliary shaft 23 through the medium of the pinion wheel 24 and gear wheel 25, and the timing .of the rotation of the shaft 23 with the shaft 21 is automati- .cally controlled in an entirely well-known manner by an automatic clutch 26 by which the gear wheel 25 becomes keyed to the shaft 23. There are moments when the shaft 23 should remain at rest, as we hereinafter explain, and hence the clutch 26 is provided so that while the gear wheel 25 may have a continuous motion the shaft23 may in its movements be timed in accordance with the requirements of the loom.

Automatic clutch control mechanism suitable for use inthe'loom herein presented is disclosed in Letters Patent No. 779,025 and 779,395, both dated January 3, 1905, to the loom described in which Letters Patent our invention has been produced as an addition or improvement.

Upon the shaft 23 is secured a cam 27 having an extended are surface 28, a projection 29 -and depressions 30, 31 at opposite sides of saicliprojection; The cam 27 will rotate with'the shaft23- andthe sha'oe of:

the periphery of'said'cam permits, through the intermediate connection presently to be described, the layto perform its two beats, the long beat and the short beat, at each op'-.

"eration and then be returned tion shown 1n Fig. 1. r

In rear of the cam 27 is provided a lever to its rear posiv32c'ompose'd of two corresponding arms or members 33 between which'and in alinement with the cam 27 is mounted on a bolt or pin smooth surfaced wheel which engages the periphery of the cam 27. The lo werendsof the members 33 of thelever arm 32 are pivotally mountedby means of a bolt or the like 36 in a bracket 37fastened to the floor or'other suitable support. The

members 33 of. the lever arm have sooured between their upper ends a sleeve 38 I I to whichthe rear end of the pitman rod 39 is secured, the forward end of said rod 39 being pivotally connected w1th ears 40 extending downwardly from the lower middle portionof the lay beam frame 14. The cam 27,

lever arm 32, and connecting rod 39 are made use ofto return the lay beam frame 14 to 1135 rear position and to tune its movements forwardly to make the beat under the action ofthe springs141 whose tension retains the roller carried. by the lever arm 32 against the cam 37 andthus. cooperates with said cam in its action on the lay beam frame.

There Wlll be two springs 41 employed, one at the inner side of each side frame of the loom, and these springs will correspondingly act against the vertical members 15 of.

the lay beam frame. The rear ends of the spr1ngs.'41 are connected with eyebolts .42 which extend through laterally turned ears of brackets 43 secured to the side frames 10, and on each bolt 42 will be provided an adjusting nut 44 and lock or jam nut 45. By loosening the j am nut 45 the nut 44 may be rotated todraw the eyebolt 42 rearwardly or release it to move forwardly in a wellknown mechanical manner, the purpose be ing to secure such adjustment of the ten sion of; the springs 41 as may be desired. The-forward ends of the springs 41 are connected by pivoted hooks 46 with the upper ends of the upper members 47 of bell crank levers 48 which are pivotally mounted on the side framesrlO and have their lower members 49 equipped with rollers 50 which I are adapted to ride on the .downwardly and exerted through the bell crank levers 48 to are surface, 28 at the roller 35.

move the lay beam frame forwardly to perform itsbeat, and said springs 41 are controlledin their action bythe cam 27. The beat of the lay is caused by the springs 41, and hence the 7 beat is cushioned. lhe springs 41 may, however, only act when the 'cam-27permits them so to do remains stationary and is held in stationary position by the cam 27, which cam at each of'its movements comes to rest when-in the position shown in Fig. 1 with one end of its After the shuttle has made its throw the shaft 23 immediately commences to rotate and carries the are surface 28 downwardly from the roller 35. and at this time the springs 41 by acting on the bell ,crank. levers 48 and members 15 of the lay beam frame, force said frame forwardlyto perform the first beat, and this movement of the lay beam frame acts through the connectingrod39 to draw the lever 32 forwardly and carry the roller 35 into the recess or depression 30 of the. cam 27, the cam thus permitting the springs 41 to make the first beat. Immediately upon the conclusion of the first beat of the lay the projection 29 rides against the roller 35 and forces the lever 32 and connecting rod rearwardly in. opposition to the stress of the springs 41 and thus returns the lay partly to its rear position. Immediately after the projection 29 of the cam 27 rides by the roller 35, the springs 41 again act on the lay and through the same cause e kiL roller 35 of the lever 32 to enter the recess or depression 31 ofthe cam 27, said recess at such time'permitting the lay to make its second or short beat. The. continued rotation of the cam 27 carries the recess 31 away from the roller 35 and brings the projecting arc surface 28 of said cam against said roller, and this has the effect of returning the lay to its rear position and of retaining thesame in such position during the next throw of the shuttle. tary stoppage of the cam 27 at the end of each of its rotations, the cam being then arrested while in the position shown in Fig. 1, and being so arrested to permit the shut- There is a momenr tle to complete its throw, and thereupon the I shaft 23 is automatically started in motion according to usual methods in looms, and the cam 27 performs another rotation and the lay is permitted under the force of the springs 41 to perform 'its long and short beats.

The novel features of our invention reside in the springs 41 with their connections for causing the lay to perform its beats, and the cam 27 for controlling the action of the springs ll and moving the lay after its beat to its rear position and there holding it while the shuttle performs its duty, the shuttle being diagrammatically indicated at 51. lVhile the lay is moving forwardly to erform its beats the rollers 50 carried by the lower members of the bell crank levers a8 ride up the inclined surfaces of the cams 19, and upon the rearward motion of the lay said rollers ride down said inclined surfaces. lVe have found very great efliciency in the employment of the bell crank levers 48 and cams 19 in connection with the springs 41 held under tension and acting against said levers.

Vhat we claim as our invention and desire to secure by Letters Patent, is:
